(Nanowerk News) University of Groningen physicists have managed to alter the flow of spin waves through a magnet, using only an electrical current. This is a huge step towards the spin transistor that ...

In 2004, electrical engineering pioneers Nick Holonyak, Jr. and Milton Feng at the University of Illinois invented the transistor laser--a three-port device that incorporated quantum-wells in the base ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Cypress's Dave Van Ess proposes a novel way of analyzing mixed-signal circuits in terms of serializing the digitized analog signal and then assesing the relative time the signal is high. As an “old ...
